- `npm run dev:docs`: Runs both the development server for your docs/demo site.

- `npm run build`: Shortcut to run both build:lib and build:docs.

- `npm run build:lib`: Production ready build of your library as an ES6 module (via UMD), ready to import into another project via npm.

- `npm run build:docs`: Production ready build of your docs site for your library. Put this build online so you can demo your library to the world and provide documentation.
